Hello.
Thank you for posting to the NI Discussion Forums.
Sometimes, more information about this error can be gathered from the DMM Soft Front Panel. This can be accessed from Start>>Programs>>National Instruments>>NI-DMM>>DMM Soft Front Panel. Once inside, are you able to take successful measurements with the device? Secondly, do you see an option under the Utility menu called Self Test? This functionality may have been added after 2.4.5. However, if you have access to it, sometimes the error messages in this place are more detailed and helpful than the error message in MAX.
Upgrading the driver to 2.7 could certainly solve the issue that you are seeing. There have been some users that had this same issue and upgrading the driver returned the system to a working state. If upgrading is not an option, could you shed some light on what your CPU is? Are you using an industrial PC? Is it over MXI (if so, which MXI)? What is the processor speed and what is the computer model number?
Finally, I would recommend possibly placing the board in another PC to see if this is a CPU issue and not a 4070 issue.
Let me know how these steps go. We will be glad to help you further!

Hello.
As part of this troubleshooting process, the PC specifications would be very helpful. Also, the way that you are communicating with the PC from the PXI Chassis is also important. If you are using MXI, what version of MXI are you using? If it is a specific computer model, that would also help us out.
Also, are you able to take accurate measurements with your 4071? As a quick test, if you hook up a battery to the 4071, can you read an accurate voltage on the Soft Front Panel?
Finally, have you tried the 4071 on any other PC's? Does it work? Does it fail with the same error?
Let us know. We will be happy to look into this issue further!
